The equation p = 31 + 1.75w models the relation between the amount of tuyet's monthly water bill payment, p, in
dollars, and the number of units of water, w, used. interpret the p-intercept of the equation.

The "P" intercept, 31, means that Tuyet's monthly water bill would be $31 if he used no water.

Step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
